This ihv-eht'ion relates toiihproveinents in means for cutting andfeeding sanitary paper coverings for closet seats;

one object ofthe invention is to provide amachine of this charabter'adapted to be applied to a closet seat for cutting paper coveringstherefor and for feeding said ooveritigs-onto'the' seats i-n positionfor use:

Another object isto provide an improved constru'ctioii or coverihg ofclosure adapted to'" be broughtinto and out of engagementwith't he seatby the'maehine- With these and other objects" in view, the

formed therefrom and" fed to an operative position over or' inengagement with the seat;- Fig; 10' is a detail perspective View ofoneof the blades of the stationary member of the-paper cutting die; Fig; P1is'a similar .iew of one oil? the paper coverings formed by the machine;

In the embodiment of the invention I provide" a niain supporting framewhich may be of any suitable shapearid which isadapted to be secured hethe rear portion of the seat 2" of the closet bowl in: any suitablemanner; In the present insta'nce'th'e frame is shown as comprisingvertical side bars 1 which areconnect'ed at theirl wer ends by a lowercrossbar 3'and at? a suitable distance above the cross bare aieconnected by an upper cross bar 4". The side bars are extended upwardlyfor I a suitable distance above the cross bar 3 and have arrangedthereon hearings to revolubly support the shaft of a roll of paper fromwhich my improve-d sanitary seat coveringsare fOI'mBd'.

Secured to the side bars lop'posite the upper cross bar 4: of the frameis a diamond shaped die supporting frame? the'lower end of whichisalso'connected tothe lower cross bar 3 of the frame by an integral'zrtehsion 8 as Show. Secured to the fro'nt sides of the" frame 7 arestationary die members" or blocks 9'which are arranged to'form' adismond shaped opening and to whio'h are se cured thestatioha'ry'cutting blades 10 of the female di'e. Adapted to. co actwith the stationary die member'of the-machine is a movable male diecomprising. a diamond-shaped frame 11 in which is arranged a centrallydisposed cross bar 12'. The bar 12 has secured thereto and therefromrods 13 which slidably engage brackets 14 in the upper cross bar 4: ofthe frame 1 and thereby support the movable member of the die inposition to be brought into operative enga 'ement with the station'- arvmember thereo which are provided near their inner ends With inwardlyextending right angular attaching lugs 16 which project inwardly andhave projecting at right angles 7 The movable member ,of the die carriesa seriesof cutting blades'15 the adjacent portions of the frame 11 bymeans of bolts 19 which are arranged in notches or recesses 20 formed inthe front side of the frame 11. The inner ends of the bolts 19 areloosely engaged with apertures in the inner walls of the recesses 20 andhave thereon adjusting nuts 21.

Arranged on the bolts 19 are coiled springs 22 the pressure of which isexerted to force the outer portions of theblades outwardly or away fromthe edges of the frame so that when the movable die member is broughtinto coa'ct-ion with the stationary die member, said blades will form apositive cutting engagement with the blades of the stationary die. Theengagcment'of the blades 15 with the stationary blades 10 of the dieblocks 9 will force said yielding or spring projected blades of themovable die member inwardly so that when the cuts are completed theblades 15 will have been forced into contact with the edges of the frame11. The blades 15 are of greater width at their inner ends than at theirouter ends, the, cutting edges of the blades tapering from said innerends toward the outer ends as clearly. shown in Figs. 7'and 8 of thedrawings. By

thus constructing the blades 15 it will be seen that when the movabledie member is brought into engagement with the station-' ary die memberthe inner ends of the blades 15 begin cutting the paper first and thepaper is gradually out toward the outer ends of the blades as the edgesthereof are brought into coaction with the outer portions of thestationary die blades, the blades thus having a shearing action whencutting the paper.

The paper from which the sanitary seat coverings are formed is unwoundfrom the roll 6 and drawn downwardly between the stationary and movablemembers of the die and is fed from the roll and the coverings formedthereon projected across the closet seat by the feeding mechanismhereinafter described. The movable die member 11 is actuated to cut anopening in the paper between said die members by an operating mechanismcomprising a short rack bar 23 secured at one end to the cross bar 12 ofthe frame 11 and which has a sliding engagement with the upper edge ofthe uppercross bar 4 of the main frame of the machine as shown."Revolubly mounted in suitable bearing brackets on the bar 4 of the mainframe is a rock shaft 24- having fiXed on its inner end a pinion 25which has an operative engagement with the rack bar 23 whereby when theshaft 24. is rocked in one direction or the other the rack bar 23 andthe movable member of the die will be projected and re tracted into andout of engagement with the stationary die" member thereby cutting theportion ofthe paper between said die members. The blades 15 of themovable die member do not come together at their lower ends, so that thecut made in the paper by the blades of the movable and stationary diemembers is not completed at the lower portion, or in other words theportion of the paper out out by the blades is not entirelysevered fromthe main sheet 'or' strip of paper so that when the portion of the sheetwhich forms the sanitary seat covering is projected over or'intoengagement with the seat of the bowl the cut outportion will hang downin the form of a tab or apron, and will cover the front edge of the holein the seat and the front inner portion of the bowl. The rock shaft 24is provided on its outer end with a short crank arm 26 to which isconnected the upper end of an operating rod or bar 27 the lower end ofwhich is connected with the paper severing mechanism of the machinehereinafter described.

After the dies have been operated to cut the opening inthe paper ashereinbefbre described the paper is fed or drawn fr 111 the roll and thecut portion thereof projected over or into engagement with the seat ofthe bowl by a paper feeding mechanism comprising. a pair of feedingrolls 28 and 29 which are revolubly mounted in the side bars of the mainframe near the lower cross bar 3 thereof. The rolls 28 and 29 areprovided with a covering of rubber or other suit able material forobtaining a firm grip on the paper. The rollers 28 and 29 are providedat one end with operating gears 30 and 31 which are normally engaged foroperating said rollers. The gear 30 on the upper roller 28 is slidablykeyed to said roller and is adapted to be shifted laterally thereon outof engagement with the gear 31 on thb lower roller 29 and out ofengagement with a.

shown. The gear 30 is shifted into and outof engagement with the gears31 and 32 by a shifting mechanism comprising a shifting bar 34 slidablymounted in a bearing bracket 35 formed on the adjacent side bar of the'frame and which is provided on its inner end with a'fork 36 adapted toloosely engage flanged hub 37 formed on the outer side of the gear 30.On the outer end of the bar 34 is secured a plug 38 having therein arecess 39 with which is loosely engaged a depending finger 40 formed onthe lower end of a gear shifting lever 41 which is fulcrumed on bearingears 42 formed on the bracket 35 as shown. By swinging the lever 41inwardly or outwardly the gear 30 will be shifted out of and intooperative engagement with the drive gear 32 and the gear .31 on thelower feed roller whereby the movement of the drive gear 32 will beimparted to said feed rollers.

The pulley shaft 33 and the drive gear 32 thereon are operated by'a'suitable driving mechanism comprising a power transmitting shaft 43which is revolubly mounted in suitable bearings in theside bars of theframe and has fixed thereon adjacent to one end a power transmitting'gaged with a pinion'45 on the adjacent end angle or inclined upwardlyfrom their To the.

downwardly at gear 44 which is enof the pulley shaft 33 as shown.Alsofixed on the shaft 43 is a sprocket gear 46 whichis connected by asprocket chain 47 with a sprocket gear 48 revolubly mounted on a stubshaft 49 which is adjustably secured in a slot 50 formed in the extendedupper portion of the adjacent side bar of the frame 1 as shown. Theupper sprocket gear 48 is provided with a crank handle 51 whereby thisgear is turned for actuating the power transmitting shaft 43 themovement of which is imparted to the pulley shaft and through the latterto the feeding rollers in the manner described for turning said rollersin the proper direction.

The cutting mechanism for severing the paper after the same has been cutby the diesand fed across or over the seat of the bowl by the feedingrollers 28 and 29 hereinbefore described, and between which the end ofthe paper is always engaged, comprises a lower cutting bar or blade 52the ends of which are pivotally connected to the lower-ends of shortoperating bars or levers 53 and 54 which are pivoted midway betweentheir ends to the side bars of the main frame of the device. To theupper end of the bar or lever 53 ispivotally connected an upper knife orcutting blade 55 while to the upper end of the lever 54 is pivotallyconnected an upper knife or cutting blade 56. The lower or cuttingedges. of knives or blades 55 and 56 are formed on an outer toward theirinner ends asshown. lower corner of the pivoted end of the blade orknife 56 is connected one end of a blade or knife operating rod 58 theopposite end of which is pivotally connected to the shank 59 of a bladeoperating handle 60 which is formed on and projects upwardly atan anglefrom the outer edge of the lever 53 and from a point midway between theends of said lever as clearly shown in Fig. 9 of the drawings. .The rod58 is offset or bent its end and the offset inner end thereof isslidably engaged with a stud 61 on the'lower outer corner of the upperblade or knife 55 as shown. By thus constructing and arranging the upperand the v lower blades of the cutting mechanism and providing .theoperating shaft; as herein shown. and described it will be seen thatwhen the handle 60 is pressed downwardly the lever 53 will be rocked andthrough the lower cutting bar or blade 52 will rock the lever 54 on theopposite side of the frame and will raise said bar or blade 52.,Simultaneously with the operation of the blade 52 the rod 58 will beactuated by the handle 60 and will swing the upper cutting blac as orknives 55-and 56 downwardly into operative engagement with the upwardlymoving lower cutting bar or blade 52 thereby severing the end of thestrip of paper which has been cut by the dies to form the seat coveringand has been projected forwardly over the seat by the feeding rollers 28and 29 hereinbefore described. The operating rod or bar 27 which isconnected at its upper end to the crank arm 26 on the rock shaft 24 hasits lower end connected to the upper end of the knife operating lever orbar 53 as shown at 62 so that when the knives or cutting blades of thepaper severing mechanism are actuated the rock shaft 24 will besimultaneously operated to project the movable member of the papercutting die into engagement w th the stationary member thereof forcutting the opening in the portion of the paper which is now between thedie members as hereinbefore described thus forming'the next seatcovering.

In connection with my improved sanitary paper coverings and the meansfor cutting and projecting the same into position over the seat I alsoprovide an especially designed cover for the seat when the latter is notin use. My improved seat cover is in thiform of an apron 63 which issecured at its outer end to and is adapted to be wound on and off asupporting roller 64 which is mounted in suitable brackets 65 secured tothe front edge of the closet seat as shown. The apron 63 which forms thecover of the seat may be constructed of leather, cloth or other suitableflexible material which may be readily wound on and off the roller. Theouter end of the apron 63 has secured thereto a binding strip 66 formedof metal or other suitable material. The apron .63 is drawn back andforth across the seat, to cover and uncover the same, by endlessoperating cords 67 which are engaged with the ends of the roller 64 atthe forward end of the seat and at the rear end of the seat areoperatively engaged with pulleys 68 fixed on the pulley shaft 33hereinbefore re ferred to and which is revolubly mounted in the sidebars of the main frame of the device. As hereinbefore described thepulley shaft 33 has fixed on its outer end a pinion 45 which isoperatively engaged with a gear 44 on the power transmitting shaft 43which is driven by the sprocket chain 4L7 and sprocket gears whichhave'also been previously described in connection with the operatingmechanism for paper feeding rollers 28 and 29. The apron operating cords67 before engaging the pulleys 68 have one stretch thereof engaged withguide pulleys 69 and the other stretch engaged with guide pulleys 70which are arranged on the base of the main supporting frame and whichhold and guide the cords so that the latter will be properly engagedwith and operated by the pulleys 68 for drawing the apron over the seatwhen the latter is not in use and which will operate the roller to drawthe apron forwardly from the seat and wind'the same on the roller 64. Inthis operation the apron is drawn from the seat f and wound up on theroller simultaneously of the apron 63 with the projection of thesanitary paper seat covering by the feeding rollers2 8' and 29, it willbe understood however that when the apron is drawn back over the seatthat it is first necessary to shift the gear 80 of the upper paperprojecting roller out of engagement with the gear 32 011 the pulleyshaft 33 so that the paper feeding mechanism will be thrown out ofoperation, while the apron is being drawn across or over the seat. Thebinding strip 66" on the outer end is suitably connected with one of thestretches of the operating-cord 67 so that when the cords are operatedin the manner described the apron will be drawn back and forth acrossthe seat.

In practicethe device will be provided with suitable casings or.coverings for inclosing the operating gears and other parts of thedevice, said coverings being omitted from the drawings to enable theparts to be more clearly illustrated.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.
